I'm putting together machines for a small company, and they wanted quiet ones. So I bought four Zalmans ZM300A, which are very nice. But they decided to add some more stuff to the fourth one, so I was thinking to get a bigger one. I want to put a ZM400A there, but can't find an online dealer that sells it. Also, any impressions for this PSU? Or recomendations for a QUIET 350W-400W PSU? I have Enermax EG361 and several Antec True330 and SL350's they're good but not as quiet as the Zalmans.
